I had to restore my phone and go to 3.1.3...I had my files saved on cydia for 3.1.2...

is there a way to tether without being jailbroken on 3.1.3? If not, would anyone be willing to help me (maybe remote in) and downgrade back to 3.1.2? I travel a bunch and this comes in handy whn in airports that all don't have the same hotspots..

everyones help is much appreciated

on a Mac BTW with most UTD OS X
